Updating wastewater treatment pathways for the Seventh Carbon Budget

Wastewater treatment emissions are a small proportion of total UK emissions, but this proportion increases by 2050 in our Sixth Carbon Budget scenarios, as other sectors largely decarbonise while wastewater emissions only fall by a small amount. Assumptions on emission reductions from wastewater in our Sixth Carbon Budget scenarios were based on academic papers and discussions with academics and stakeholders in the water industry. This resulted in emission reductions of 20% by 2030 in three of our scenarios, includ...
